Hey there @EvelynWaugh 
Welcome to DevKinsta community!
Just wanted to check if your MyKinsta user role/permission is set to “Site Access (Site Developer)” ?
if that so, please kindly ask someone from your MyKinsta company (that has higher/proper permission) to set/change your MyKinsta user role/permission there to be “Site Access (Site Administrator)” instead and see if you’re then able to see the site list on your DevKinsta (in that Pull/Import from Kinsta list) - as I also mentioned the same in the other thread here 
Cheers,
Agus
